Automatic Speed Tip for 1/8" & 5/32" Welding Rod. The automatic speed tip is threaded into the barrel and the welding rod inserted into the feeder tube. Once the welding rod adheres to the base plastic the user may let go of the welding rod, if s/he so chooses, and the boat of the tip will automatically pull the welding rod through. This tip is recommended for long welding runs to help reduce fatigue on the user. The narrow body style allows the user to get into tight areas and corners easily.
